Nonrefillable closure



March 19, 1935. A. TiVOLI NONREFILLABLE CLOSURE 1 Filed Dec. 11, 1953 2 Sheets-Sheet 2 Inventor HUBER Patented Mar. 19, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in containers of the non-refillable type, and more particularly to a novel form of closure which when once positioned will prevent the refilling of a container on which the closure is located.

The principal object of the present invention is to provide a non-refillable container closure which will preclude the possibility of refilling regardless of in whatever position the container is placed.

Another important object of the present invention is to provide a non-refillable container closure of the type specified which will be positive acting in operation and not susceptible to the development of ready defects.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a vertical sectional view through the neck portion of a container and through the novel non-refillable closure associated therewith.

Figure 2 represents a sectional view taken substantially on line 22 of Figure 1.

Figure 3 represents a side elevational view of the closure core.

Figure 4 represents a. side elevational view of the valve elements.

Figure 5 represents a sectional view taken substantially on line 5-5 of Figure 1.

Figure 6 represents a bottom plan view of the weighted valve element.

Figure '1 represents a sectional view taken substantially on line 77 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1' that numeral 5 represents a container, such as a bottle, provided with a neck portion 6. In adapting the bottle for the present invention, the inside of the neck 6 is provided with a circumferentially extending groove 7.

The closure structure consists of a cylindrical member 8 having a metallic and thread formed lining 9 for receiving the threaded plug or stopper 10 which is provided with a corrugated head or knob portion 11 at its upper end.

This lining 9 is provided with a depending skirt portion 12 which has a circumferentially extending grooveway in its outer side and when the cyl-.- inder 8 is properly positioned within the neck 6 of the bottle, this grooveway 13 will register with the grooveway '1 in the neck 6 and the split spring ring 14 will spring into the groove 7 of the neck to interlock the skirt and neck of the bottle toperforated partition in the neck,

gether, so that it is impossible to remove the lining and cylinder 8 without breaking the neck or the bottle. This skirt portion 12 is provided with a constricted depend ng portion 15 forming a valve seat 5 for the conical valve element 16. This constricted portion 15 merges with a. vertically slotted cylindrical portion 1'7 which in turn merges with an outwardly flaring seat portion 18 for the stop element 19 which is hollow and has a cross piece 20 therein from which extends a rod 21 through the apex portion of the valve element 19 to anchor in the valve element 16 in the manner substantially shown in Figure 1. The stop element 16 has a recess therein for slidably receiving the guide pin 23 which depends from the plate 24. This plate 24 is supported by short connectors 25 depending from the perforated partition plate 26 crossing the interior of the skirt 12 below the threaded portion or lining 9. 26

It can now be seen that once the closure is inserted into the neck 6, the same cannot be removed. When the bottle is inverted to permit pouring of its contents, the contents will flow out through the slots in the slotted portion 17 and out through the perforated partition 26, provided, of course, the stopper 10 has been removed. During this operation, the valve element 19 seats in the seat 18. Should an attempt be made to force liquid under pressure into the container, with the container inverted, the pressure will, of course, act against the valve element 16 and will seat the same, completely shutting off the interior of the container from the neck 6.

Obviously, nothing canbe forced into the container regardless of in what position the container is positioned.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:-- 45 In a non-refillable bottle having a neck and a gravitatable valvehaving a guideway therein; a

a plate supported by the partition in spaced relation below the same, said plate having an out-turned edge portion spaced from the inner side of the neck, and a guide projection on the bottom side of the said plate for engagement into'the guideway of the valve.
